Nortel Secure Router 8000 Series Configuration -WAN Access 6 PPP and MP configuration Configuring Authenticator with a user name. The authentication procures are as follows: - Authenticator sends a random generated "challenge" message together with the local host name to the peer. - The peer looks for its local password in the local users list based on the user name of authenticator.

Nortel Secure Router 8000 Series Configuration -WAN Access 6 PPP and MP configuration NCP negotiation supports IPCP, MPLSCP and OSCICP negotiations. IPCP negotiation involves the negotiation of IP addresses of two ends. After NCP negotiation, a network layer protocol is selected. The network layer protocol then sends messages over the PPP link.

It defines three layers starting from physical layer to packet layer.

Nortel Secure Router 8000 Series Configuration -WAN Access 7 LAPB and X.25 configuration 7.1.2 X.25 Principle Virtual Circuit By using the X.25, you can connect two DETs through the existing telephone network. A virtual circuit (VC) is the created connection in X.25 to ensure reliable communication between two DTEs. A VC only exists logically, which is different from physical circuit in circuit switching.

Nortel Secure Router 8000 Series Configuration -WAN Access • 7 LAPB and X.25 configuration After being set up, PVC continues in the stage of data transmission without the process of call establishment and call deletion. Therefore, X.25 load balancing is ineffective on PVC and functions only on SVC. Within a single X.25 hunt group, all DTEs hold the identical status and share the same X.121 addresses. The DTEs in a hunt group can call other DTEs outside the hunt group in the normal mode.
PAGE 211
Nortel Secure Router 8000 Series Configuration -WAN Access 7 LAPB and X.25 configuration • In round-robin mode, cyclic selection method is adopted to select the next interface or the XOT Tunnel for every call request. For example, as shown in the above figure, if hunt group hg1 adopts round-robin mode, calls are sent to Server A and Server B in turn. • The VC-number mode selects the interfaces with free logical channels in a hunt group for every call request.

Nortel Secure Router 8000 Series Configuration -WAN Access 7 LAPB and X.25 configuration Setting X.25 VC range • VC Management The X.25 protocol can multiplex multiple number of logical virtual connections over a physically existing link between DTE and DCE. The virtual connections are called VC or logic channel (LC). The virtual connections established by X.25 reach a maximum of 4095, and their numbers range from 1 to 4095. LC Identifier (LCI) or VC Number (VCN) differentiates each VC (or logic channel).

Nortel Secure Router 8000 Series Configuration -WAN Access 7 LAPB and X.25 configuration To set up a SVC with a call, you need an X.25 address which adopts the address format specified in ITU-T Recommendation X.121.

Nortel Secure Router 8000 Series Configuration -WAN Access 7 LAPB and X.25 configuration An X.25 interface has its X.121 address and inter-network protocol (such as IP) address. When X.25 initiates a call through this interface, the source address (calling DTE address) carried in the call request packet is the X.121 address of this interface. For a datagram with a definite destination IP address, you locate its corresponding X.121 destination address by the configured address mapping.

Nortel Secure Router 8000 Series Configuration -WAN Access 10 Low-speed ATM configuration Figure 10-1 ATM protocol model The AAL is responsible for forwarding the information between the ATM Layer and the upper layer protocols. The following are the four types of AAL: AAL1, AAL2, AAL3/4 and AAL5. Each of these supports certain special services. Most of the ATM equipments use AAL5 to support the data communication service. The ATM also has the QoS mechanism.
